| 摘 要： | 在石家庄和天津两城市,施用芜菁夜蛾线虫Steinernema feltiae agriotos Filitjev防治小木蠹蛾 Holcocerus insularis Staudinger。经防治的树计1.4万棵,用塑料洗涤瓶将线虫悬液(1000条/ml)从最上端虫孔注入,每树约注200ml。线虫注入虫道后,有大量木蠹蛾幼虫感病爬出树干外死亡。死亡率达96.8%,活幼虫孔减退率为94.2%。大面积用线虫防治小木蠹蛾的显著效果说明,芜菁夜蛾线虫防治小木蠹蛾可应用于生产上。

| Abstract: | About 14000 shade trees infested by carpenterworm Holcocerus in-sularis in Shijiazhuang and Tianjin Cities were injected with 200 ml/tree entomopathogenic nematode Steinernema feltiae agriotos suspensioncontaining 1000 larvae/ml into the uppermost bore on the trunk.Mas-sive infected carpenterworms gushed out from the bores a few daysafter inoculation,and died around the trunk.The mortality was up to96.8% and the suvivor's bores was 94.2% decreased.The result indic-ated that the preparation of this strain of entomophytic nematodes isa potential biological control agent for effectively suppressing this ca-rpenterworm species. |
